Abstract:
A method for fabricating and forming a continuous covered area, such as a sidewalk or patio, employing vertically interlocking tessellated components. One embodiment, termed PORTAPAVE™, achieves this interlocking via an array of uniquely configured two-sectioned pavers. Each paver has a first section of a first shape and a second section of a second shape impressed upon the first section and bonded together. In one embodiment, first sections of pavers are installed in a bottom layer to form a cavity between them having the same shape as the second section of a paver that is inverted onto the pavers of the bottom layer, thus providing a top layer. Each inverted paver in this top layer is fitted to interlock in that cavity formed between the un-inverted pavers in the bottom layer.
Abstract:
A paving block with a rubber piece made from, e.g., a used tier, for reducing echoes, noise, wear, icing on the block surface, adhering force of ice, shocks in collisions, etc. The block having high dimensional accuracy and comprising strong rubber piece that does not peel away fro a long period is provided by a simple and low-cost method. The method is applied to provide diverse construction blocks to which materials, other than rubber, with various characteristics are attached. A square piece of rubber is cut off from a tire with non-uniform, uneven thickness caused by wear. This piece of rubber is made a surface layer piece (1) of a block, and asphalt that functions as a bonding portion (2) is applied to the back side of the surface layer piece (1). Concrete is placed directly on the asphalt as a curing body (3). The concrete placement thickness is adjusted so that the entire block has a predetermined thickness and the concrete is cured. Using a holding arm (7), a net like member (5), a separator (33), a joint (34), etc. can increase the strength of the block.

Landscaping/building tile systems comprising a plurality of individual tiles secured by a plurality of interlocking fastening strips. In one aspect, the tile systems comprise a plurality of tile sections, each of which includes a plurality of individual tiles, that can be secured together to form a single, unitary mat.
Abstract:
A pre-fabricated concrete slab system and method have matching rectangular male and female type slabs which fit adjacent to each other in a checkerboard fashion. The male slabs include spaced reinforcing rods extending longitudinally and transversely through the male slabs with the rods' distal ends protruding outwardly away from one or more side edges of the male slabs to form a plurality of male connectors. The female slabs include a plurality of corresponding female sockets on one or more sides of the female slab, each female socket receiving a corresponding male connector when dropped therein. Corresponding female sockets positioned on opposite side edges of the female slabs are interconnected by steel reinforcing bars in both the longitudinal and transverse directions in a configuration similar to the male slabs so that, when connected, a continuous tension reinforcement is established between male and female slabs in both the longitudinal and transverse directions.
Abstract:
In the manufacture of an articulated, predominantly concrete mat, which comprises concrete blocks and a flexible geogrid embedded in such blocks and in which the flexible geogrid defines flexible members connecting such blocks to one another, an intermediate article being a concrete slab is cast, in which a flexible geogrid is embedded. The slab has relatively thinner portions, along which the slab is breakable to form such blocks, and relatively thicker portions, which become such blocks when the slab is broken along the relatively thinner portions. The relatively thicker portions are arranged in parallel rows and are staggered in adjacent rows, before the slab is broken therealong, and the relatively thicker portions in alternate rows are aligned in parallel columns, before the slab is broken therealong.
Abstract:
In an assembly of predominantly concrete revetment, each revetment is a generally rectangular solid having two longitudinal margins and two transverse margins, having two expansive faces, and having an array of apertures, which extend through said revetment, between the expansive faces, and through which vegetation can grow. Each revetment has a grid of embedded reinforcing bars, which include a reinforcing bar extending within each of its longitudinal and transverse margins. Each revetment has, on each of its longitudinal and transverse margins, one or more ribs extending between its expansive faces. At each rib on each of its longitudinal margins or at each rib on each of its longitudinal and transverse margins, each revetment has a cable passage extending through such rib and through the longitudinal margins has such rib and opening into a near aperture of the array of apertures of said revetment. The revetments are connected to one another, via cables passing through at least some of the cable passages of the connected revetments, so that at least some of the ribs of the connected revetments approximate one another. The approximating ribs are adapted to become crushed, so as to minimize crushing of the connected revetments except at the approximating ribs, if and when the assembly is articulated at the approximating ribs.

Abstract:
A system for installing segmental masonry paving units commonly referred to as pavers. The pavers are arranged into patterns then adhered to a flexible grid with handles that can be cut away after installation. This paving system provides a prearranged pattern using multiple paving units which are flexible, easy to handle, and easy to install. They can be constructed with any type and color of masonry paver unit, and in some cases patterns are specifically designed for the system.
Abstract:
1. Paving stone set and process and device for the manufacture thereof.2.1. In the case of lawn-paving blocks formed from paving stones (10) spaced at a considerable distance apart, these are joined together, against relative displacements, by a holding grid (11) embedded in the paving stones (10) and comprising tension-resistant strands. The said holding grid allows the transfer of traction forces and hence the reciprocal safeguarding of the paving stones (10) within a paving stone set held together by the holding grid (11).2.2. The manufacture of the paving stone sets is effected in a concrete stone mold which is conventional in its principle. A flask (19) disposed on a molding plate (28) and a drawing sheet (29) is divided in the horizontal plane (33), creating a top part-flask (34) and a bottom part-flask (35). The holding grid (11) is clamped between the two part-flasks during pouring of the concrete. Following the completion of a paving stone set, the bottom part-flask (35) is withdrawn from the concrete stone mold. Demolding can now be carried out in the usual manner.
Abstract:
A wire grid shaped with brick size spaces which may be transported or stored as a roll, and which is adaptable for serving as a permanent guide and reinforcement when unrolled onto a flat path with bricks subsequently individually mounted in each of the grid spaces.
